Dental Etchant Compositions Comprising One Or More Dentin Collagen Cross-Linking Agents, Methods Of Producing The Same, And Methods Of Use

Abstract

Dental etchant compositions, processes for making the same, and methods for using the dental etchant compositions are disclosed. The dental etchant compositions include at least one acid and one or more dentin collagen cross-linking agents. The methods for using the dental etchant compositions may include contacting a mammal's tooth with a dental etchant composition that includes one or more acids and one or more dentin collagen cross-linking agents.

What is claimed is: 
     
         1 . A dental etchant composition comprising: at least one acid; and one or more dentin collagen cross-linking agents. 
     
     
         2 . The dental etchant composition according to  claim 1 , wherein the one or more dentin collagen cross-linking agents comprise one or more polyphenols. 
     
     
         3 . The dental etchant composition according to  claim 2 , wherein the one or more polyphenols comprise one or more proanthocyanidins. 
     
     
         4 . The dental etchant composition according to  claim 1 , wherein the at least one acid comprises phosphoric acid, and wherein the phosphoric acid is present in an amount of at least about 1 wt. % and no more than about 40 wt. %. 
     
     
         5 . The dental etchant composition according to  claim 1 , wherein the one or more dentin collagen cross-linking agents are present in at least one of a plant extract or a plant seed extract, and wherein the at least one of a plant extract or a plant seed extract is present in an amount of at least about 0.1 wt. % to no more than about 15 wt. %. 
     
     
         6 . The dental etchant composition according to  claim 1 , wherein a pH of the dental etchant composition is less than about 2. 
     
     
         7 . The dental etchant composition according to  claim 1 , further comprising one or more rheology modifiers selected from the group consisting of: silica, polyvinyl alcohol, and a combination thereof. 
     
     
         8 . A process for the production of a dental etchant composition, the process comprising: combining at least one acid with one or more dentin collagen cross-linking agents to form a dental etchant composition. 
     
     
         9 . The process according to  claim 8 , wherein the one or more dentin collagen cross-linking agents comprise one or more polyphenols. 
     
     
         10 . The process according to  claim 9 , wherein the one or more polyphenols comprise one or more proanthocyanidins. 
     
     
         11 . The process according to  claim 8 , wherein the dental etchant composition has a pH of less than about 2. 
     
     
         12 . The process according to  claim 8 , wherein the at least one acid comprises phosphoric acid, maleic acid, citric acid, or a combination thereof. 
     
     
         13 . The process according to  claim 8 , wherein the one or more dentin collagen cross-linking agents are present in at least one of a plant extract or a plant seed extract, and wherein the at least one of a plant extract or a plant seed extract is present in an amount of at least about 0.1 wt. % to no more than about 15 wt. %. 
     
     
         14 . A method for performing a dental restoration on a mammal's tooth, the method comprising: contacting at least a portion of a mammal's tooth with a dental etchant composition, the dental etchant composition comprising: one or more acids and one or more dentin collagen cross-linking agents; and removing at least a portion of the dental etchant composition from the mammal's tooth. 
     
     
         15 . The method according to  claim 14 , wherein the dental etchant composition is present on the mammal's tooth for at least about 15 seconds. 
     
     
         16 . The method according to  claim 14 , wherein the one or more dentin collagen cross-linking agents comprise one or more polyphenols. 
     
     
         17 . The method according  claim 14 , wherein the one or more acids comprise phosphoric acid, maleic acid, citric acid, or a combination thereof. 
     
     
         18 . The method according to  claim 17 , wherein the one or more acids comprise phosphoric acid in an amount of at least about 1 wt. % to no more than about 40 wt. %. 
     
     
         19 . The method according to  claim 14 , wherein the one or more dentin collagen cross-linking agents are present in at least one of a plant extract or a plant seed extract. 
     
     
         20 . The method according to  claim 19  wherein the at least one of a plant extract or a plant seed extract comprises grape seed extract, wherein the grape seed extract is present in the dental etchant composition in an amount of at least about 0.1 wt. % to no more than about 15 wt. %.
